Summary

Belkin Bulldog Plus version 4.0.2 build 1219 contains a stack-based buffer overflow vulnerability in its web service authentication handler. When a specially crafted HTTP request is sent with an oversized Authorization header, the application fails to properly validate the input length before copying it into a fixed-size buffer, resulting in memory corruption and potential remote code execution.

Risk Assessment

An attacker with network access can remotely execute arbitrary code without authentication, potentially leading to device compromise. This can compromise the confidentiality and integrity of the system.

Recommendation

Update Belkin Bulldog Plus to a newer version if available, or isolate the device from untrusted networks. Monitoring for exploitation attempts is also recommended.

Belkin Bulldog Plus version 4.0.2 build 1219 contains a stack-based buffer overflow vulnerability in its web service authentication handler. When a specially crafted HTTP request is sent with an oversized Authorization header, the application fails to properly validate the input length before copying it into a fixed-size buffer, resulting in memory corruption and potential remote code execution. Exploitation requires network access and does not require prior authentication.
